I’m always worried about trying something radically different in our projects. What if it doesn’t go to plan? What if there’s something we haven’t considered? Those concerns were completely unfounded with UFAD. it was far less complex, and way easier to plan and install than a traditional system.

What is UFAD?

UFAD (underfloor air distribution) is an innovative air distribution approach that is growing in popularity amongst commercial architects and mechanical engineers. Because of its improved air quality, cost-effectiveness, design flexibility and energy efficiency, it is quickly becoming a preferred solution for heating and cooling office buildings — for both new constructions, and renovations.

Unlike overhead VAV systems, underfloor air distribution systems are designed to work with the laws of physics — not against them. In a UFAD system, conditioned air is supplied through floor diffusers instead of ceiling diffusers.

Benefits of UFAD

Overhead HVAC is fundamentally flawed. It’s more expensive, less efficient, and completely inflexible. And it’s remained virtually unchanged since the advent of the commercial HVAC industry in the 1950s.

UFAD delivers massive cost-savings compared to overhead systems — from construction all the way through to the HVAC system’s life-cycle.

Air Quality

UFAD results in less cross-contamination of air between occupants, compared to traditional overhead VAV


Installation Costs

UFAD uses fewer materials and special equipment for installation; and reduced first cost by up to 10%, with 15% faster build and completion times

Engineering Time

UFAD requires 80% less time to detail in BIM

Energy Usage

UFAD saves up to 30% in fan energy use and requires 20% less outside air than conventional overhead VAV

Mechanical Spaces

UFAD can help you reclaim up to 10% of the square footage lost to mechanical spaces

Floor Heights

For every 12 standard floors, UFAD can free up enough vertical space to add an additional floor to your building

Building Value

Buildings with RAF and UFAD qualify for accelerated tax depreciation opportunities, along with a minimum 10 LEED credits


UFAD mechanical systems are hidden out of sight beneath raised floors, and adapt to any building design and any architectural style.
